HOOF-TRlNlNllNG DEVICE.

Specification of Letters Patent.

Eatented May 21, 1907.

Application filed December 5, 1906. Serial No. 346.499.

To all whom, t may concern.-

Be it known that l, BERRY HUCKLEBY, a citizen of the United States,residing at Bonham, in the county of Fannin and State of Texas, haveinvented new and useful lmprovements in Hoof-Trimming Devices, of whichthe following is a speciiication.

This invention relates to hoof trimming devices of the type employed forpreparing animals hoofs in the operation of shoeing, and has for itsobject to provide a comparatively simple, inexpensive device of thischaracter which may, in practice, be readily manipulated, one wherebythe hoof may be quickly and accurately trimmed, and one which may beconveniently adjusted for varying the depth of the'cut to be effected.

With these and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings: Figure 1 is a reverse plan view of atrimming device embodving the invention. Fig. 2 is a side sectionalelevation, the section being taken on the line 2 2 of Fig. 1.

Referring to the drawings, it will be seen that the frame of the devicecomprises a pair of upper side bars of rails 1 inclined forwardly andinwardly throughout a portion of their length and connected at theirforward ends, which extend in substantially parallel relation, by meansof a cross head 2, there being arranged in a plane beneath that of therails 1 a central, longitudinal guide rail 3, which projects a suitabledistance beyond the forward end of the frame in which it is connected ata point between its ends by means of a perpendicular post 4 and at itsrear end through the medium of diagonally inclined end members or bars5, preferably formed integral with the side rails 1.

Arranged for endwise reciprocation on the guide rail 3 is a travelermember or slide 6 provided at its rear end with transverse bearing ears7 to which are pivoted operating levers 8 fulcrumed between their endsas at 9 to the forward ends of links 1() in turn pivoted at their rearends to the bars .5, there being provided at the forward end of thetraveler transversely projecting ears 11, to which are pivoted theforward ends of knife carrying members or bars 12 bolted or otherwisedetachably engaged at their rear ends with inwardly projecting trimmingknives or blades 13 extended transversely of the bars 1 to 4which theyare slidably connected by means of clip plates 14 bolted or otherwisedetachably engaged with the knives which are provided with sharpenedforward cutting edges 15.

Arranged in the frame above the rail 3 is an' adjustable hoof supportingmember or lever 16 provided at a point between its ends with abifurcated bearing portion 17 arranged to straddle the rail 3 at a pointin rear of the traveler 6 for the reception of a transverse pintle 18 bymeans of which the lever is pivoted, there being projected rearwardlyfrom the bearing head 17 and to lie beneath the rail 3 a portion or arm19 slotted at 2O for the reception of a thumb screw 21, in turn threadedthrough the rear end of the rail 3 and operable for adjusting theforward end of the lever 16, which is bifurcated to straddle and rideupon the post 11.

In practice, the operating levers 8 normally stand in forwardlydiverging position with the traveler 6 retracted and the knives 13 lyingat the rear ends of the rails 1 and spread apart as illustrated by fulllines in Fig. 1. Under these conditions, the animals hoof to be trimmedis seated between the forward parallel portions of the rails 1 with thetoe bearing against the cross head 2 and the bottom of the hoof restingon the lever 16, which by manipulating the screw 21 may be adjusted toregulate the depth of the cut to be effected. After the lever 16 hasbeen properly adjusted the outer ends of the operating members 8 aregrasped and swung rearwardly,' thereby sliding the traveler 6 forwardlyon the guide rail 3 for moving the knives forwardly on the rails 1, itbeing noted. that during such movement of the knives they will, owing tothe inclination of the rails, approach toward each other, whereby theywill, at the completion of their forward movement, meet for properlytrimming the toe of the hoof.

It is to be particularly observed that in the operation of the devicethe marginal edge of the hoof will be quickly and accurately trimmed andthat in the action of the knives they will be properly moved fortrimming the horny portion of the hoof around but without injuring thefrog.

Having thus described my invention, what l claim is:

1. In a hoof trimming device, a frame including a pair of forwardlyconverging side rails and a central, longitudinally extending IOO IIO

guide rail7 a traveler slidably mounted on said guide rail, operatinglevers fulcrumed in the frame and operatively connected with thetraveler, cooperating trimming knives *slidably mounted on the siderails, and operative connections between the knives and traveler. v

2. In a hoof trimming` device, a frame including a pair of forwardlyconverging side rails and a central, longitudinally extending guiderail, a traveler slidably mounted on the guide rail, a pair ofcooperating trimming knives slidably mounted on the side rails andconnected for movement with the traveler7 a pair of operating leversfulcrumed in the iframe and operatively connected with the traveler, andan adjustable hoof supporting member movably mounted in the frame.

In testimony whereof, I aHiX my signature in presence of two witnesses.
